Unit Identifier Switches
Two Unit Identifier (UID) Switches and two
LED Indicators are located on the mother-
board. The Rear UID Switch (JUID) is located
next to LAN 2 port on the backplane. The
Front Panel UID Switch is located at Pin 13
of the Front Control Panel. Connect a cable
to Pins 13/14 of JF1 for Front Panel UID
Switch support. The Front Panel UID LED
is located at Pin 7 of JF1, and the Rear UID
LED is located at LE2. When you press the
front or rear UID switch, both Rear UID LED
and Front Panel UID LED Indicators will be
turned on. Press the UID switch again to turn
off both LED Indicators. These UID Indicators
provide easy identification of a system unit
that may be in need of service.
Note: UID can also be triggered
via IPMI on the X8DTU-F moth-
erboard. For more information on
IPMI, please refer to the IPMI User's
Guide posted on our website @
